I thought about some kind of badge/shirt/harness for Frodo for quite a while. Then I moved out here and we have service dogs in training that come into our store quite often.

If anything having something on the dogs seem to make MORE people come up and want to read it or chat or try to pet the dog (people are such morons)! Heck people come up to Frodo and I occasionally JUST to ask why he has a muzzle on. It's not a muzzle, it's a Gentle Leader. But if it WAS a muzzle shouldn't that tell you that maybe approaching might not be the best option?

I find it easier to just be aware of our surroundings and tell people he doesn't like to be touched by strangers. It's pretty easy to tell when people are thinking about coming up to pet him, even when they haven't asked.
